Basic Instructions for Hatching Blue Bottle Larvae

1. Prepare a Hatching Container

   • Use a well-ventilated container with a lid to prevent escape.
   • Add a moisture-retaining filler like coco fiber, sphagnum moss, or the included filler to maintain humidity.

2. Maintain Proper Humidity

   • Lightly mist the filler with water to keep it damp, but not soaking wet.
   • Higher humidity helps speed up the hatching process.

3. Temperature Requirements

   • Keep the container in a warm area, ideally between 75–85°F (24–29°C).
   • Avoid direct sunlight or extreme temperature changes.

4. Time to Hatch

   • Under ideal conditions, larvae will pupate and hatch into flies within 7–14 days.
   • Higher humidity and warmth can speed up the process, while cooler, drier conditions may slow it down.

5. Feeding Newly Hatched Flies

   • Once hatched, provide a food source like sugar water or fruit to keep the flies active and healthy.

6. Troubleshooting

   • Too slow? Increase warmth and humidity.
   • Too dry? Lightly mist the filler to maintain moisture.
   • Not hatching? Give them more time and check environmental conditions.
